if else inside for loop in c but else statement doesn't work-CodePudding

for (int i = 1; i < 22; i  ){
        
    if(i<=99 && i>=0){
        printf("enter an age");
        scanf("%d", &ages[i]);
    }
    else{
            printf("enter a valid number");
    }
       
}

When I enter a number outside the if statement such as 999, my program still accepts it instead of printing enter a valid number message. thanks in advance.

I think as the 'i' is the index of the 'ages' array, you are allowing values with a range of 0-99. So, if the value is out oof this range also, it will still be stored in the 'ages' array. It won't display the warning message (enter a valid number) also. Instead, you can try something like this:

for (int i = 0; i < 22; i  ){
    printf("enter an age: ");
    scanf("%d", &ages[i]);
    if(ages[i] > 99 || ages[i] < 0){
        printf("enter a valid number\n");
        i--;
    }
}
